  • Method and device for controlling a tank ventilation device for a motor vehicle
    Patent number: 8584654
    Abstract: A method for controlling a tank ventilation device (102) for a motor vehicle (100) is proposed in which first of all a tank vent valve (28) of the tank ventilation device (102) is closed. Then, the value of a control signal for the tank vent valve (28) is increased in the sense of an opening of the tank vent valve (28) until a leak detection means (23, 31) associated with the tank ventilation device (102) recognizes a leak in the tank ventilation device (102). The value of the control signal at which the leak in the tank ventilation device (102) is recognized is identified as the opening control value for opening the tank vent valve (28). In this way, the opening control value for the tank vent valve (28) can be determined with a high frequency and precision.
